在毛主席无产阶级革命路线指引下,我校轮机系从一九七○年试制成功油泵油嘴,先后自制成功10万转/分高速风动磨头、高速台钻等二十多台专用设备,并生产出上万套喷油嘴偶件,有力地支援了渔业生产,深受广大渔民的欢迎与赞扬。随着高速风动磨头试制成功,基本解决了喷油嘴体加工工艺过程,产量和质量都有相应的提高,但因缺少精度较高的外圆磨床,喷油嘴针阀阀座的磨削加工,其光洁度和几何形状精度均达不到产品精度要求。过去针阀阀座磨削加工,是在滚动轴承结构磨头架进行,因主
Under the guidance of Chairman Mao’s proletarian revolutionary line, our school’s turbine department successfully piloted and manufactured oil pump nozzles in 1970 and has successively manufactured over 20 sets of special equipment such as high-speed bench drill and drilling rig with high speed of 100,000 rev / min. And produced tens of thousands of sets of nozzle even, effectively supporting the fisheries production, welcomed by the majority of fishermen and praise. With the high-speed pneumatic grinding head trial success, the basic solution to the nozzle body processing technology, production and quality have a corresponding increase, but due to the lack of high precision cylindrical grinder, nozzle needle valve seat grinding Cutting, its finish and geometry accuracy are not up to product accuracy requirements. In the past needle valve seat grinding is carried out in the roller bearing structure grinding head frame, due to the Lord
